The distinction between "walking" and "hiking" is a bit arbitrary. Most of my walking trips have been long-distance, continuous point-to-point journeys. But none have involved backpacking. My first experiences with backpacking were with the Boy Scouts in the 1950's and then with the US Army in the 60's. When I moved to Georgia in the early 70's I hiked in the north Georgia mountains, as well as Tennessee and North Carolina. Most of this hiking was on the Appalachian Trail, and Great Smoky Mountains National Park. When I moved to Colorado from Georgia, I did a number of trips in the Rocky Mountains. But as I grew older, I tired of the burden of heavy packs and heavy boots.
In recent years, the "Go Lite" changes in equipment have restored my ability and interest in doing multi-day hiking trips. The weight of my pack has dropped from 40-50 lbs to 20-25 lbs. thanks to new equipment. My footwear has changed as well as I gave up leather mountaineering boots for lighter weight leather/mesh footwear. I'm just getting started on my new lightweight adventures, thanks to the advice and inspiration from world-class hiker Andrew Skurka (see http://andrewskurka.com/) Here is a list of recent trips.
